Kurtosis is a measure of the "tailedness" of the probability distribution of a real-valued random variable.

kurtosis(x, na.rm = FALSE)

# S3 method for default
kurtosis(x, na.rm = FALSE)

# S3 method for matrix
kurtosis(x, na.rm = FALSE)

# S3 method for data.frame
kurtosis(x, na.rm = FALSE)

Arguments

x	a vector of values, a matrix or a data frame
na.rm	a logical value indicating whether NA values should be stripped before the computation proceeds.
